## Report
Today, during my TEEP internship, I focused on presenting a comprehensive plan on how xApp can effectively implement pre-registration and pre-authentication to achieve load balancing in the Open RAN system while optimizing the workload on the 5G core.

I began the presentation by explaining the current challenges faced by the 5G core due to the increasing number of connected devices and data traffic. The 5G core is responsible for handling authentication, registration, and other essential functions, which can lead to bottlenecks and performance issues as the network becomes more congested.

To address these challenges, I proposed the implementation of pre-registration and pre-authentication in xApp. Pre-registration involves the process of registering a UE with the OpenRAN before it reaches the 5G core. This allows the OpenRAN to handle initial authentication requests, reducing the workload on the 5G core significantly.

Next, I delved into the concept of pre-authentication, which involves authenticating a UE at the OpenRAN before reaching the 5G core. By implementing pre-authentication, the OpenRAN can quickly and securely handle the authentication process, leveraging its proximity to the UE. This not only improves the overall authentication speed but also ensures a smoother and more efficient user experience.

Throughout the presentation, I supported my proposals with relevant research and industry examples, demonstrating the potential impact of implementing pre-registration and pre-authentication on the Open RAN ecosystem.

## Comment
Overall, the presentation went well, and I received positive feedback from the audience and mentors. The concept of leveraging pre-registration and pre-authentication to balance the load and improve authentication speed in the Open RAN resonated with the team. Some questions were raised about the potential challenges in implementing these solutions across different network configurations, but I addressed them effectively by emphasizing the flexibility and adaptability of xApp.

## Further Plan
1. Conduct an in-depth analysis of different network configurations to anticipate any potential challenges in the implementation of pre-registration and pre-authentication.
2. Collaborate with the TEEP team to develop a proof-of-concept (POC) for the proposed solution and evaluate its effectiveness in a controlled environment.
3. Engage in discussions with industry experts and potential users to gather feedback and insights that can further enhance the proposal.
4. Work on refining the presentation and exploring additional use cases where pre-registration and pre-authentication can bring significant benefits to the Open RAN ecosystem.
